4) Walter usually meets Julia at the track. He prefers to jog 3 miles. From long experience, he knows that σ = 2.40 minutes for his jogging times. For a random sample of 90 jogging sessions, the mean time was 22.50 minutes. Let μ be the mean jogging time for the entire distribution of Walter’s 3-mile running times over the past several years. Find a 0.99 confidence interval for μ.

Crepe Creations is considering franchising its unique brand of crepes to stall-holders on Hermoza Beach, which is five miles long. CC estimates that on an average day there are 1,000 sunbathers evenly spread along the beach and that each sunbather will buy one crepe per day provided that the price plus any disutility cost does not exceed $5. Each sunbather incurs a disutility cost of getting up from resting to get a crepe and returning to their beach spot of 25 cents for every 1/4 mile the sunbather has to walk to get to the CC stall. Each crepe costs $0.50 to make and CC incurs a $40 overhead cost per day to operate a stall. How many franchises should CC award given that it determines the prices the stall holders can charge and that it will have a profit-sharing royalty scheme with the stall holders? What will be the price of a crepe at each stall? Suppose now that CC requires that each stall holder deliver the crepes in its own designated territory. How many franchises should now be awarded if we make the standard assumption that the effort costs of the stall holders are the same as those of the sun bathers? How would your answer change if the the stall holders instead incurred effort costs half as much as those of the sun bathers, that is, if their costs were 12.5 cents for every quarter mile of distance?

Demand and supply are Key elements of the U.S. economic system. So, too, is competition. This exercise will challenge you to better understand the ethical dimensions of a system that relies on demand, supply, and competition.

The Situation

You are a businessperson in a small town, where you run one of two local pharmacies. The population and economics base are fairly stable. Each pharmacy controls about 50 percent of the market. Each is reasonably profitable, generating solid if unspectacular revenues.

The Dilemma

You have just been approached by the owner of the other pharmacy. He has indicated an interest either in buying your pharmacy or in selling his to you. He argues that neither of you can substantially increase your profits and complains that if one pharmacy raises its prices, customers will simply go to the other one. He tells you outright that if you sell to him, he plans to raise prices by 10 percent. He believes that the local market will have to accept the increase for two reasons: (1) The town is too small to attract national competitors, such as Walgreens, and (2) locals customers can’t go elsewhere to shop because the nearest town with a pharmacy is 40 miles away.

Questions for Discussion -

1. What are the roles of supply, demand, and competition in this scenario?

2. What are the underlying ethical issues?

3. What would you do if you were actually faced with this situation?

2. The table below gives information on the distance from various nearby towns to the famous Cupcake Town Lake (distance is in miles). There is no admission fee. The only cost of visiting Cupcake Lake is the travel cost, which costs $1/mile. The researcher estimates the relationship between the number of visits per capita (per person), x, and the one-way travel cost from the town in which people live, p. He finds this demand function to be: x = 30 – 1.2*p .

CITY OF ORIGIN POPULATION DISTANCE

ALABASTER 2000 12

BEAUTIFUL 4000 18

CORNUCOPIA 3000 20

DELIGHT 5000 30

(a) What is the cutoff price (the price at which demand falls to zero) with this demand function?

(b) Add columns to the table above identifying the cost of a visit to Cupcake Lake from each town, the predicted number of visits per capita from that town, and the total number of visits from the town (i.e., the visits per capita multiplied by the population).

(c) Why doesn’t the researcher observe anyone coming from certain places to Cupcake Lake?

(d) The authorities decide to make improvements at Cupcake Lake (they build a boathouse), which only residents of Alabaster are allowed to use. In consequence, Alabaster resident’s 2 demand function for Cupcake lake changes to x = 50 – 1.2p. The demand functions of residents of the other towns do not change. What is the economic value of this improvement to Alabaster residents?

Natalie is also thinking of buying a van that will be used only for business. The cost of the van is estimated at $38,500. Natalie would spend an additional $2,500 to have the van painted. In addition, she wants the back seat of the van removed so that she will have lots of room to transport her mixer inventory as well as her baking supplies. The cost of taking out the back seat and installing shelving units is estimated at $1,500. She expects the van to last her about 5 years, and she expects to drive it for 100,000 miles. The annual cost of vehicle insurance will be $2,400. Natalie estimates that at the end of the 5-year useful life the van will sell for $6,500. Assume that she will buy the van on August 15, 2015, and it will be ready for use on September 1, 2015. Natalie is concerned about the impact of the van’s cost on her income statement and balance sheet. She has come to you for advice on calculating the van’s depreciation. (what impact will the three methods of depreciation on Natalie's balance sheet at December 31 2017)
